This is what I’m doing at the moment too, so I’ll tell you what I do!
When I fancy having my hair curly, I either wash it or dampen my hair then twist and tie it in a bun for the night, in the morning I wake up, take out the hair band, and I have curly hair! I either have my hair half up half down, braid sections of my hair and bobbi pin it back. You can do millions of things with curly hair to create a romantic, playful look.
For wavy hair simple braid all your hair and take out in the morning, it can be massive so make sure you braid they are loose plaits! 😛
For messy/beach hair I wrap my hair in a loose bun and careful back comb sections in the morning, its also very easy and manageable hairstyles quick for the hectic morning! Im really into the messy look at the moment so I normally have messy high bun, messy ponytails and messy side plaits. Even clipping your loosely twisted fringe looks so cute and creative!
For more different and creative hairstyles either simple type into YouTube or google ‘heat free hair styles’ you should get MILLIONS of results. That’s what I did, and Ive learnt so many cute, quick easy hairstyles that I would never have thought of!
Hope I helped!
